Arizona 84

Arizona 84 is a short connecting road between Casa Grande and Interstate 8. The road was first designated as a state highway in 1927, but has been grown and truncated over the years.

The original highway was designated in 1927 between Casa Grande and Tucson, paralleling the Southern Pacific Railroad line. The road was extended west to Gila Bend in 1930, effectively turning Arizona 84 into a shortcut for thru traffic between San Diego and Tucson traveling U.S. 80.

In time, Arizona 84 would become the primary thru route, which led to the demise of most of the road. When the route for Interstate 10 was laid out between Phoenix and Tucson, it followed Arizona 84 between Casa Grande and Tucson, as the route was shorter than U.S. 80 through Florence. Interstate 8 was designed to overlay the rest of Arizona 84.

In 1966, Interstate 10 between Eloy and Tucson was completed, truncating Arizona 84 at Eloy. The original road exists as a frontage road today.

In 1974, Arizona 84 was decommissioned between Gila Bend and the present-day terminus at Interstate 8 exit 151.

In 1997, Arizona 84 between downtown Casa Grande and Arizona 87 was decommissioned. Today, the signed route travels between Interstate 8 and downtown Casa Grande, and the unsigned route travels between Arizona 87 and Interstate 10.
